is there a certain way of tightening the nuts on the headers, like top to bottom or left to right or any other way because i hear leaks but im not sure if its my cat or the headers???
Okay I know whats happened - Mitsubishi have two different bolt diameters on the end of the heads a 8mm or 10mm and what has happened is that the headers have all been done to the same 8mm diameter.
What you will need to do is on some model cars (And we are not sure which ones exactly) you need to drill out the two lowest side holes (One on each side) out slightly larger to fit over teh stud on the cylinder head.
I think the galants run the two larger holes but the eclipses run the smaller holes, but if we drill them out to the large size then on the cars with the smaller holes it makes a small fitment.
Note this size hole is only on two of the total of 10 studs which is why it is hard to pick.
Glad to hear you got it sorted out.

No there is no particular sequence - it is best if possible that you refit the exhaust manifold gasket with a sealer but not absoloutly necessary.

I got the header, looks great! what is it made out of? In other words is it going to rust or should I get it dipped (porcelain or ceramic)? Is it necessary to dip to prevent rust for this header?
They are made out of mild 3mm thick steel.
We have run them on cars without coating them and have had no rust problems but being located in the USA - I beleive a lot of firms have rust problems with salt on roads etc so if you have the money get them ceramic coated if possible - if not then fit them up and get them done later which you can do.

I am sending them to my local machinist to have my block acid dipped, he said he would also ceramic coat the header so I am gonna go for it.
